Ask ten landlords whether to buy in a personal name or a limited company and you will get ten confident, contradictory answers. The truth is that neither structure wins universally; the right choice depends on your tax band, your portfolio plans and how long you intend to hold. What has changed decisively is the default: before 2017 most landlords bought personally, while today most new portfolio purchases happen through companies. Understanding why tells you whether you should follow. Our buy-to-let mortgages page covers how lenders treat both structures.
Why Did Limited Companies Take Over Buy-to-Let?
The turning point was Section 24 of the Finance (No. 2) Act 2015, phased in from 2017. It replaced the old system where mortgage interest was deducted from rental income before tax with a flat 20% tax credit on finance costs. For basic rate taxpayers the effect was roughly neutral, but higher rate taxpayers lost most of their interest relief, pushing profitable properties into taxable losses on paper. Companies were left untouched: corporation tax applies to profits after full interest deduction, which is why leveraged landlords migrated.
Who Benefits Most From Company Ownership?
Higher or additional rate taxpayers buying with mortgages gain most, because the interest deduction survives intact inside a company. Landlords planning to grow a portfolio also benefit, since profits retained within a company can fund future deposits without extraction taxes. Basic rate taxpayers without mortgages often lose out: corporation tax plus dividend taxation when extracting profits can exceed simple income tax on rent received personally. Running costs matter too, as companies carry accountancy fees, confirmation statement filings and sometimes more expensive lending.
How Does SPV Lending Work?
Lenders adapted to the migration by building products for special purpose vehicles, companies set up purely to hold property. Underwriting focuses on the asset rather than the individual: rental coverage is stress tested at typically 125% to 145% of the payment, and directors provide personal guarantees alongside limited liability for the debt itself. Rates run modestly above personal names, though the gap has narrowed considerably as volumes have grown. HMOs, multi-unit blocks and portfolios sit naturally in this world, where specialist lenders assess commercial reality rather than tick-box affordability.
Is a Limited Company Always the Better Structure?
No. Consider three common situations. A basic rate taxpayer buying one unencumbered flat to hold long term usually keeps things simple personally. A higher rate taxpayer building a geared portfolio almost always benefits from incorporation from day one. An existing personal-name portfolio presents the awkward case: transferring properties into a company triggers stamp duty and potentially capital gains tax, and whether that one-off cost justifies ongoing relief depends on leverage, tax band and holding period. Run the numbers both ways over five years before moving anything.
What Do Lenders Require From Company Borrowers?
Standard requests include the company's registered details, proof all shareholders and directors are named, trading history where the company exists, and personal guarantees from directors owning above a threshold, commonly 20% to 25%. Some lenders insist each SPV holds only one property; others happily lend across multi-vehicle structures. Getting these requirements matched before applying avoids weeks wasted with incompatible lenders.
Should You Restructure Before Your Next Purchase?
If your next acquisition is funded by bridging or development capital, decide the end structure first, because refinancing later into the right vehicle is far cheaper than correcting afterwards. Tell us about your portfolio, your tax position and your plans, and we will map the practical route across Manchester, Leeds and beyond, then confirm indicative terms from lenders who welcome your chosen structure, usually within one working day.
